An information processing apparatus calculates, in a case of adding a new magnetic tape to a storage pool, the number of magnetic tapes to be added to the storage pool such that a free capacity of the storage pool after addition of the new magnetic tape is set to be equal to or larger than a capacity obtained by adding, to an assumed value of a total capacity of data to be recorded in the storage pool, an excess according to the number of pieces of parallel processing when recording data in the storage pool, the number being equal to or smaller than a number obtained by multiplying the number of magnetic tapes satisfying an insufficient capacity of the storage pool by the number of pieces of parallel processing, and performs control of adding the calculated number of new magnetic tapes to the storage pool.
